PANEL STOVE-TOP.

Specification of Letters Patent.

Patented Sept. 14, 1915.

Application filed November 9, 1914. Serial No. 871,213.

To all whom it may concern:

Be it known that I, THOMAS E. Form, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented a new and useful Panel Stove-Top, of which the following is a specification.

My invention relates to stove tops, such as are used on large hotel ranges and the like. The tops of such ranges are commonly composed of a rectangular frame in which are placed a plurality of movable plates. commonly constructed the rectangular frame is provided with an internally projecting ledge upon which the plates are placed, these plates extending over the fire and supporting the various cooking vessels thereon. As the intensity of the fire varies greatly these plates are subject to extreme variations in temperature and as they arecommonly constructed of cast iron considerable expansion and contraction takes place therein, due

to these variations in temperature. If the plates are made to fit tightly inside the frame when cold, they will in expanding tend to buckle and crack, and if they are made a loose fit in the frame, open cracks will be left when the plates are cold in which grease and dirt collect.

The principal object of the invention is to provide a stove top in which movable plates may be used and in which the plates will be so supported on the top that no breakage or buckling of the plates will occur when they are expanded by heat. In the ordinary types of construction the buckling of the plates results in a variation of the level of the plates so that utensils cannot be supported evenly thereon and so that ledges are formed which prevent such utensils from being readily moved around on the top of the stove.

A further object of the invention is to so construct a stove top that it will be level and all the plates will be of the same height even when they are extremely hot.

Further objects and advantages will be made evident by the following specification. In the drawings which are for illustrative purposes only: Figure 1 is a plan view of a cook stove, a portion thereof being broken away to illustrate the internal construction of the same. Fig. 2 is a section on the plane Copies of this patent may be obtained for m m of Fig. 1. Figs. 3 and 4 are enlarged sections on the plane w w of Fig. 1, Fig. 3 showing a section of the stove plate and frame in the position they assume when the parts are cold, and Fig. 4 illustrating the same parts in the position they assume when subjected to heat.

As illustrated in the drawing a stove top is provided consisting of a rectangular frame 1 in which are placed a plurality of plates 2, 3, 4, 5, and 6. The frame 1 is preferably formed of iron and may have the section illustrated in Figs. 2, 3, and 4. The inner edge thereof is formed in ogee shape as illustrated at 7, this ogee extending completely around the inside of the frame 1 as shown by the dotted lines 8 in Fig. 1. The stove plates 2 and 6 have similar ogees formed on their ends 9 and on their sides 10. The stove plates 3, 4, and 5 have the ogee formed on the ends 11 only, the edges 12 of all the plates being straight and at right angles to the surface thereof.

The plates are made of such a size that they fit loosely in the frame when cold, assuming the position shown in Fig. 3. When heated the plates expand and their ogee edges slide over the ogee edges of the .frame, the parts assuming the position shown in Fig. 4. The ogee shape has a peculiar efficiency in that it allows the plates to slide on the frame without binding and at the same time it has a fiat middle portionwhich prevents the plates from tipping.

I claim:

A panel stove top comprising a rectangular frame having an ogee shaped ledge around the inner edge thereof, end plates having a reverse shaped ogee edge on one side and both ends and a square edge on the other side, and a series of intermediate plates each independently supported on said frame and each having square edges on both sides and a reverse shaped ogee on both ends engaging the ledge on the inner edge of the frame.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 3rd day of November, 1914.

- THOMAS E. POTTS.
